Flange stabilizer for a shaped article of fiber material, shaped article, method for making a shaped article, and use of a flange stabilizer

Abstract

A shaped article, a method for making it, and its use. The shaped article is formed from flat fiber material and has a bottom ( 2 ), a body ( 4 ), and an opening, which is surrounded by a circumferential flange ( 6 ). The shaped article ( 1 ) comprises a flange stabilizer ( 10 ) attached to the second flat side ( 18 ) of the flange ( 6 ) facing the bottom ( 2 ). The flange stabilizer ( 10 ) is disc-shaped and has an inner contour ( 12 ) corresponding to the desired cross-sectional shape of the shaped article ( 1 ) in the region of the opening and can be slipped over the body ( 4 ) in the region of the bottom ( 2 ) and up to the flange ( 6 ). The flat sides ( 16, 18 ) of the flange stabilizer ( 10 ) extend essentially parallel to the flange ( 6 ), defining and stabilizing the cross-sectional shape of the body ( 4 ) in the region of the opening and the flange.

The invention claimed is: 
     
       1. A shaped article which is shaped from a flat fiber material and has a bottom ( 2 ), a body ( 4 ) and an opening, the opening being surrounded by a circumferential flange ( 6 ), characterized in that the shaped article ( 1 ) comprises a flange stabilizer ( 10 ) which is attached to a second flat side ( 18 ) of the flange ( 6 ) facing towards the bottom ( 2 ), the flange stabilizer ( 10 ) being disc-shaped and having an inner contour ( 12 ) which corresponds to the desired cross-sectional shape of the shaped article ( 1 ) in the region of the opening and can be stripped over the body ( 4 ) in the region of the bottom ( 2 ) up to the flange ( 6 ), wherein flat sides ( 16 ,  18 ) of the flange stabilizer ( 10 ) extend essentially parallel to the flange ( 6 ) and wherein the flange stabilizer ( 10 ) defines and stabilizes the cross-sectional shape of the body ( 4 ) in the region of the opening and the flange ( 6 ). 
     
     
       2. The shaped article according to  claim 1 , wherein the shaping has been performed by compression drawing. 
     
     
       3. The shaped article according to  claim 1 , wherein the flange stabilizer ( 10 ) is connected to the flange ( 6 ) by frictional fitting, gluing, sticking or sealing, wherein for sealing the flange ( 6 ) is configured as a sealing rim. 
     
     
       4. The shaped article according to  claim 3 , wherein a lid ( 26 ) is sealed onto the sealing rim to close the opening. 
     
     
       5. The shaped article according to  claim 1 , wherein the flange stabilizer ( 10 ) is cut out of a flat fiber material or plastic and with closed inner contour ( 12 ) and closed outer contour ( 14 ). 
     
     
       6. The shaped article according to  claim 1 , wherein at least the inner contour ( 12 ) of the flange stabilizer ( 10 ) is circular or oval and the flange stabilizer ( 10 ) has a web width ( 15 ) of 3 to 5 mm. 
     
     
       7. The shaped article according to  claim 1 , wherein at least the inner contour ( 12 ) of the flange stabilizer ( 10 ) is shaped other than circular or oval and the flange stabilizer ( 10 ) has a web width ( 15 ) of 4 to 10 mm. 
     
     
       8. The shaped article according to  claim 1 , wherein the inner contour ( 12 ) and the outer contour ( 14 ) differ from each other in such a way that a projection is formed.
